Title: Treatment of organic matter-containing water
Inventor: ONO SHIGERU
IPC: C02F1/72
Filed: 1986-05-30
Abstract: PURPOSE:To decompose TOC in raw water and to regenerate high-purity water by adding excess hydrogen peroxide and ferrous salt or ferric salt to org. matter-contg. water to effect an oxidation decomposition reaction, then radiating UV rays thereto to reactivate the residual hydrogen peroxide. CONSTITUTION:The excess hydrogen peroxide of 5-10 times, by weight, the total org. carbon content in the raw water and the ferrous salt or ferric salt of 3-5 times said content are added to the raw water contg. org. compds. such as alcohol and acetic acid, more particularly the dilute org. waste water discharged from a plant for producing semiconductors, etc., to effect the oxidation decomposition reaction. The UV rays are in succession radiated to the water to reactivate the hydrogen peroxide remaining in the raw water by which the residual undecomposed org. matter is decomposed by oxidation. More specifically, the TOC-component in the raw water is first decomposed 60-70% by using the hydrogen peroxide and iron salts and further the hydrogen peroxide remaining in the raw water is effectively utilized for the decomposition of the residual undecomposed org. matter, by which the regeneration of the high- purity water is realized.

Title: Automatic gain controller for am radio receiver
Inventor: HAYASHI SHIGEYOSHI
IPC: H03G3/20
Filed: 1983-07-09
Abstract: PURPOSE:To reduce the time constant of a filter and to increase the AGC response speed by performing the subtraction by a subtractor between the outputs of an AM wave detector having a peak holding function and an AM wave detector having no peak holding function and obtaining a signal containing virtually no AC component in response to the intensity of a carrier wave signal. CONSTITUTION:A subtractor 12 performs substraction between wave detection signals of an AM wave detector 8 having a peak holding function and an AM wave detector 10 having no peak holding function. Thus the difference between both signals is detected. This difference is turned into a signal which contains virtually no modulated wave component and is proportional to the intensity of a carrier wave signal. The AGC voltage obtained by transmitting the output of the subtractor 12 through an amplifier 14 and a filter 15 is turned into te DC voltage. Furthermore the value of this DC voltage is proportional to the intensity of the carrier wave signal. The AGC signal is applied to a frequency mixing circuit 4 and an intermediate frequency amplifying circuit 6 as the control input. Thus the gain is automatically controlled.

Abstract: PURPOSE:To form a higher-output semiconductor laser element with excellent yield by a method wherein a thin-film layer, which transmits light, is formed on the major surfaces of the light-emitting surface. CONSTITUTION:Cleavage lines 22 are cut in the crystal located at one edge of a wafer 12 by applying an external force to the one edge of an fixed interval with a knife, etc., and after that, the wafer 12 is parted at each of intermediate parts between grooves 14, and furthermore, a cracking is performed at the lines 22 for forming semiconductor laser chips 23.

Title: Laid block
Inventor: OIKAWA ITARO
IPC: C05G5/14
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of propagating plants by allowing their roots to grow. SOLUTION: A laid block F is manufactured by hardening of fluid concrete and is laid on the ground surface of a face of slope, etc. In this case, powders of charcoal M are mixed, and useful microorganisms are contained therein. Because of the intervention of the relatively soft charcoal M, the roots of plants are easy to grow by breaking the charcoal M itself or passing through gaps around the charcoal. The charcoal M is easy to hold nutrients and can therefore supply sufficient nutrition sources to the roots, thus promoting the growth of the roots and allowing the plants to propagate with higher reliability. Since the useful microorganisms exist in the concrete and charcoal M, the growth of the plants is further promoted by the action of the microorganisms, ensuring propagation of time plants and allowing the plants to be firmly rooted in the ground.
